The invention relates to an amphibious aircraft buoy, a stamping die and a manufacturing method. The amphibious aircraft buoy is in a hull shape and is formed by hot stamping of a thermoplastic composite material, and the thermoplastic composite material is composed of thermoplastic resin and reinforced fibers. The stamping die comprises an upper die body, a lower die body, a positioning device and a blank clamping device, the opposite surfaces of the upper die body and the lower die body are provided with a male die structure and a female die structure which are complementary, the positioning device is fixed to the lower die body, and the blank clamping device is used for clamping a blank to be stamped and formed and positioning the blank through the positioning device. And the blank is positioned and supported right above the female die structure. The manufacturing method comprises the following steps of providing a stamping die, preparing a blank, heating the blank, performing hot stamping and performing trimming treatment. The amphibious aircraft buoy has the advantages of high strength, fatigue resistance, impact resistance, damage tolerance and the like.
